[0020] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.
[0021] like Figures 1 to 6As shown, an injection mold for a lower cover of a water storage tank of a washing machine in this embodiment comprises a mounting plate 1 and a main body 2, and the main body 2 and the mounting plate 1 are connected by a locking assembly 3, so that the main body 2 can be easily disassembled and assembled with the mounting plate 1 through the locking assembly 3, and the main body can be easily replaced. The mounting plate 1 is provided with a positioning portion 11, and at least two positioning portions 11 are arranged at intervals, and the main body 2 is locked by the positioning portion 11 in cooperation with the locking assembly 3. The positioning portion 11 comprises a first groove 111 and a second groove 112, and the first groove 111 and the second groove 112 are arranged alternately, and the first groove 111 longitudinally penetrates the first side wall 12 and the second side wall 13 of the mounting plate 1, and one end of the second groove 112 is connected to the third side wall 14 or the fourth side wall 15 of the mounting plate 1. The locking assembly 3 comprises a locking member 31 and a fitting member 32, and the fitting member 32 is slidably arranged in the first groove 111 or the second groove 112, and the locking member 31 passes through the main body 2 and is threadedly connected with the fitting member 32. The locking member 31 in this embodiment is a bolt, and the fitting member 32 is a nut. In the above technical solution, the main body 2 is fixed to the mounting plate 1 by the locking member 31. When the sizes of different main bodies 2 are different, the positions of the fitting members 32 in the grooves can be adjusted to adapt to different main body installations. The above technical solution can facilitate the installation of the mounting plate and main bodies of different sizes.
[0022] In this embodiment, the first groove 111 and the second groove 112 have the same structure. The groove has a contraction portion 113, so that the fitting 32 in the groove can be limited. The locking member 31 passes through the contraction portion 113 and is connected to the fitting 32. The cross section of the groove in this embodiment is T-shaped. In each positioning portion 11, there is one first groove 111 and multiple second grooves 112. The multiple second grooves 112 are arranged in parallel. The second groove 112 is perpendicular to the first groove 111, which facilitates the fitting to adjust its position in the groove.
[0023] In this embodiment, the main body 2 includes an upper mold 21 and a lower mold 22. The lower mold 22 has a through hole 221. The through hole 221 is arranged corresponding to the first groove 111 or the second groove 112, so that the lower mold 22 can be locked with the mounting plate 1. The upper mold 21 and the lower mold 22 are connected by a fixing assembly 4. The fixing assembly 4 includes a first fixing member 41, a second fixing member 42, a positioning piece 43, a first nut 44 and a second nut 45. The first fixing member 41 is threadedly connected to the screw hole 211 of the upper mold 21 through the first nut 44, and the second fixing member 42 is threadedly connected to the screw hole of the lower mold 22 through the second nut 45. The first fixing member 41 and the second fixing member 42 are the same fixing members, the first nut 44 and the second nut 45 are the same nuts, and the positioning piece 43 is clamped between the nut and the end portion 411 of the fixing member. The positioning piece 43 has a first hole 431 and a second hole 432. The inner diameter of the first hole 431 is larger than the end portion 411, and the inner diameter of the second hole 432 is smaller than the end portion 411. The first hole 431 and the second hole 432 are connected by a groove body 433. When the fixing assembly 4 is used, the first and second fixing members are threadedly connected with the nut after passing through the first hole 431, and then connected with the screw holes of the upper and lower molds. By rotating the nut, the gap between the end portion 411 and the nut can be adjusted to adapt the thickness of the positioning piece 43. The positioning piece 43 is moved so that the end portion 411 moves from the first hole 431 to the second hole 432 to clamp the positioning piece. Since the inner diameter of the second hole 432 is smaller, the positioning piece 43 can be prevented from being disengaged. Through the above technical solution, the positioning piece can be easily positioned and released, and the locking and release of the upper and lower molds can be facilitated. The positioning piece 43 is provided with a bracket 46, and the bracket 46 is provided with an identification plate 47. The identification plate 47 can be used to identify information such as the mold model.
[0024] The injection mold for the lower cover of the water tank of a washing machine of the present embodiment can facilitate the adaptation and installation of the mounting plate with the main bodies of different sizes. In addition, it can facilitate the locking and releasing of the upper mold and the lower mold for easy replacement.
[0025] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
